Will these work in a 1in14 twist?

Difficult to say Dan, you know I am no expert mate but....

They are designed for Palma shooting which are (If I am correct) is usually around 13". Your rifle (I am convinced) has been barrelled for the old tight RG bullets that were .306 ONO.

They may well be OK mate I dont know, but they should do OK in a 13".

I keep having people point out to me that I should not be using hybrids in my Dolphin at 13", but they have so far produced the best results. Did OK in the Euros and can just about hold my own...as long as I get my head out my arse and centre the damned group Muppet!!

If you look at Brian Litz's info on the Hybrid, the 155.5, the Sierra 2156, and the HBC (all 155gr ONO) none of them are stable in all conditions in a 13" twist, and I dont believe for one minute that people shooting palma are not using these bullets.

I think the yanks under egg the pudding....so they dont get sued :55:

Interestingly although the HBC seems to have an agressive Secant Ogive, and is one point off the BC for the 155.5, it is shorter than the hybrid, so should be more stable, and I bet it goes well.

Steve Thornton does well with them, and a couple of Spanish guys in the Euros did very well with HBCs

The thing is that this is the ONLY bullet they produce, so they can tune everything to producing one, decent (I hope) match bullet.

I have 200 on order for testing (I will work up loads with 2 or 3 different powders if they work well with my standard, just in case the sceptics buy up everything....they cannot hoover up all the Vhit as well, surely to god!!)

OK, so 200 of said bullets arrive from Foxy very well packed at £60 + very reasonable P&P.

On initial inspection they look fine.

It was commented to me recently that they had little rings and marks and this is true if you look for them, but they are very fine and you cannot feel them, I can only assume that had they been tumbled in the same cement mixer as Berger they would be equally as shiny. The surface finish is very consistent.

Another thing that struck me as I counted them (They came in a plastic bag and I want them into 100 boxes, so I counted them as they went through the pointing die, nothing to do with trusting fox I assure you), was firstly just how crisp the meplats were, but also the fact that there was not one that was bent over, bashed in, or looked like it was picked off the floor.....again common in my experience with more expensive bullets.

Pointing? Yes, they are quite large meplats (sorry, I did not measure them, I am sure its out there somewhere) and I point as a matter of course as a final audit, it means I have to handle each bullet (with loading gloves of course...I have rusty fingers!!!).

So its weighing time.

Generally 195 fell into a band between 154.89 and 155.24. About a 40/40/20 split 154.89-155.09/155.10-155.19/155.20-155.24.

Half a dozen or so were mongs....155.30-155.42....foulers sorted then

Better than any bullet I have yet batched (Bergers 155.5 and hybrids and Sierra 2156).

So onto bearing surfaces then.

A very quick task this as the whole lot (even the foulers) fell between 0.564-0.5655....every single one, bust.

I have to admit that I only measured ogive to base, but that alone was consistent enough to be encouraging and I am no Laurie Holland, I used one of Ovenpaas comparators, but I dont have the boat tail section for measuring the pure BS as yet.

So it looks encouraging.

One final thought, I could not help comparing them with a 155 Hybrid, to the naked eye they look very, very similar, although shorter (the HBC is said to have better stability in a 13" twist than the Hybrid). BC is of course lower, but with my shooting.....

So, ideally its 2 tests with my normal band over N140 and IMR4895 at 200 on sunday with COLs to follow.

Those I know who use these have found they work ok about 10 thou off, so I will load them as I do my 2156 which is pretty close.

I will keep you posted with a very rudimentary load test zzzzom

Good luck :-)

Thanks for posting that.

Will look forward to the results.

Just hope it dont rain too much.

I need some grouping practice anyway.

The point of using 2 powders is simple, you cant rely on any supplies these days, and I used to use H4895 for the longer ranges with N140 shorter (The N fills the case nicely and works well, the H is pokey...er and more stable for the longer range stuff (past 600) but is more or less extinct, I have some but I wont be shooting a season on 1lb ).

Ideally I would like one decent load and be done with it (which is what I am hoping IMR/HBC will provide, it spits the hybrids out at 3080 no worries) with backup plans if the yanks fail to grow up!!

The ideal would be a totally Euro load and a totally yank load....anyone know of a Euro equivalent to a CCIBR4?

And I heartilly object to the price of some of the bullets that it appears one "Has" to shoot with to be any good :55:

I think Laurie Holland has tested them - maybe he will comment if he sees the post.

A few of the F/TR guys at Diggle use them - well worth a try and Foxy usually has plenty in stock.

OK, so I went out and did my least fave activity, load testing.

It does not seem to matter what I do, I always lose on out of a group, I am just poor at it...ah well.

So I tend to ignore the odd round out of 5, and it was very old brass (11 firings with some sick primer pockets...why kill new stuff on load tetsing).

But,

Both groups that were on my usual loads were better than I ever achieved with bergers or 2156, first try, ideal.

Both sub .25moa elevation at 200, (0.206 and 0.236)although I am not sure if the lateral spread (still near .5moa) is me or as was suggested COL, but I have to massage that a bit yet.

I always struggle shooting off of gravel, although it was better this time.

No idea about velocities as that stage, I want to do some long range stuff first and mess with the COLs before I start messing with come ups etc.

That said, I would shoot a short range comp with the N140 load tommorrow, it really was that good (4 under a finger nail with one left).

So far, looking very impressive.

That's good news mate! :)

Maggot,

It is about time we had a real alternative to being held to ransom by the yanks tesnews

Just curious mate but how do you feel you are being "held to ransom by the Yanks"? I've seen that written a few times on here and always wondered how folks come to that conclusion.
